Personally, I’m hugely in favor of moving llvm’s source hosting to github at some point, despite the fact that I continue to dislike git as a tool and consider monotonicly increasing version numbers to be hugely beneficial.
The killer feature to me is the community aspects of github, allowing people to get involved in the project more easily and make “drive by” contributions through the pull request model. Github also has a very scriptable interface, allowing integration of external bug trackers etc into the workflow (which is good, because its bugtracker is anemic).

Yes, it would be great to get out of this business.

If we made this change, I think we should only change one thing at a time: change source hosting, but not phabricator or the bug tracker. We could then discuss moving off phabricator to the github PR model, etc.

This works pretty well. The major problem is with tests that are flakey.
